The zirconium dioxide has no irritation and anaphylactic reaction to gum, is very suitable for being applied to oral cavity, avoids adverse reactions such as allergy, irritation, corrosion and the like generated by metal in the oral cavity, has extremely low heat conducting property, light weight and is more comfortable for patients to wear.
The zirconium dioxide porcelain tooth has unique aesthetic property, good light permeability, is close to a real tooth, and has no radiation blocking effect like other porcelain teeth. The color of the base crown of the zirconium dioxide ceramic is tooth white, so that the neck part cannot become black, darken and turn green, and the problem that the metal porcelain crown is most difficult to solve is solved. The zirconia full-ceramic tooth has the advantages of high mechanical strength, high hardness, high wear resistance, high corrosion resistance and the like, breaks through the limit of the traditional ceramic tooth, does not need to be supported by metal at all, is completely made of biological ceramic, is far away from various electromagnetic wave interferences in life, and does not leave hidden danger.
Titanium is nontoxic, light, high in strength and excellent in biocompatibility, is a very ideal medical metal material, can be used as an implant implanted into a human body, and particularly has higher strength level, better incision performance and toughness and is more suitable for being used as an implant. The titanium alloy porcelain tooth is mainly a porcelain tooth material between a noble metal porcelain tooth and a nichrome porcelain tooth, the porcelain tooth has good affinity to human body in strict sense, the material is more suitable for the requirement of human health, the service life of the material is greatly beyond the imagination of people, in theory, the service life is lifelong only by paying attention to correct teeth, the binding force of the titanium alloy and ceramics is good, the titanium alloy porcelain tooth has the characteristics of difficult porcelain breakage and durability, the biocompatibility of the titanium alloy is good, and the color change of surrounding tissues is not caused.
The traditional method for preparing the false tooth at present is usually hot-press molding after high-temperature melting, the method usually involves manual oral cavity impression, and when the tray is taken out from the mouth of a patient, precision errors can be generated, so that the manufactured dental restoration is not closed, the comfort of the patient and the wear resistance, mechanical strength and service life of the false tooth are affected, the required surface characteristics of the false tooth are printed out through laser scanning and the appearance characteristics of the tooth engaged with the false tooth, the occlusion degree of the false tooth can be enhanced, the false tooth closely attached to the dental bed of the human body can be processed, and the wear resistance, acid-base resistance and mechanical strength of the false tooth are improved.
The hydroxyapatite is a main inorganic composition component of human bone tissue, calcium and phosphorus can be released out of the surface of the material to be absorbed by the body tissue after being implanted into a human body, new tissue grows, the material is healthy and bright and white, dental plaque can be removed, tooth decay is prevented, breath is freshened, and gum problems are improved.
Graphene is one of the materials with highest known strength, and has good toughness, and the implantation of carboxyl ions can enable the surface of the graphene material to have active functional groups, so that the cell and biological reactivity of the material is greatly improved. Graphene is more easily doped and chemically modified in a chiffon shape, and is more easily accepted as a functional group.
Fullerenes are the third allotrope of elemental carbon found. The fullerene has a similar structure to graphite, but the structure of the graphite has only six-membered rings, and five-membered rings possibly exist in the fullerene, so that the surface of the fullerene material has active functional groups, the cell and biological reaction activity of the material is greatly improved, and the fullerene is easy to dope and chemically modify, so that the functional groups are easier to accept.
The biological material must meet the special requirements of macrostructure, microstructure and chemical composition to have osteoinductive property, the pores in the interconnected porous structure are an important feature, a protective area without strong fluid movement can be provided, so that cells have enough space to generate new bone along the porous channel, the porous channel after the surface is plated with the hydroxyapatite film can show better osteoinductive property, and the base shows better osteoinductive property from a thin-to-thick pore structure compared with the traditional uniform pore structure.
